My MiL really should have just said she wasn't feeling well enough to go out. It was just a waste of time and money to take her really as she spent most of the time napping.

But yeah, the driver really had no excuse for delivering the parcel to the wrong house. Our house number is clear on both doors and garden gate and the doorbell has our names on it. I really think he was just being lazy and couldn't be bothered to walk to get here.
